BUCKLE.

Application filed May 12, 1919.

To au Lo/wm 'it may concern.'

Be it known that I, BENJAMiN F. Onr- WILER, a citizen of the United States, resid ing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Buckles, of which the following is a specification.

The invention relates to improvements in buckles and has especial reference to apparel buckles for corsets, garters, Suspenders and the like.

One of the objects of the invention is to provide a buckle structure which will cleave to the fabric, in adjusted position, and which will`not creep or Walk down the web, as a result of application of abnormal strain and subsequent release of the web, as common in so many buckles of this t pe.

Another object of the invention is to improve the structure to the end that the buckle may be unusually thin, not much thicker'- than the three thicknesses of the webbingT .to which `it is shown to be attached and which is notdeflected to bringthe one reach of the fabric in the same vertical plane with ann other reach thereof.

Another object is to provide a buckle that will, with equal efficiency, coperate with thick and thin webbing without requiring change of buckle structure, and another object is to generally improve buckle structures, to cheapen the cost of construction and to reduce the number of required parts to ultimate simplicity.

Other, further and more specific objects of the invention will become readily apparent,

to persons skilled in the art, from a consideration of the following description when taken in conjunction with the drawings, wherein Figure 'l is an elevation of a buckle attached to a piece of fabric, or webbing.

Fig. 2 is a section taken on line 2-2 of Fig. l, showing the buckle closed.

`ig. 3 is a similar section showing the buckle open.

Fig. 4 shows the two parts, the frame an d the clamping lever, of which the buckle is composed.

Flg. 5 s an enlarged section, similar to Fig. 2, showing more clearly the parts as they appear when the buckle is closed.

In all the views the same reference char acters are employed to indicate similar parts.

The buckle is composed, preferably, of two parts, made of sheet metal, comprising, in

Specification of Letters Patent.

teeth 9. These teeth, it will be observed, are

located in a plane higher than the edge of the back bar, and they cooperate with the interdental spaces between the teeth of the lever ld, to permit the same to pass beyond the front bar, to which reference will be hereafter more specilicallymade. The clamping; member l is provided with a part l0, which I shall call a lever and a part ll, which I shall call the locking member' and along the edge of the locking member ll, are teeth l2. At the ends of clamping,1 member I3 are wings 13 to be formed into sleeves that are to surround the pintle bar 7, thereby providing a means by which the member B is pivoted to the member A.. The wings 13 are bent around the bar i', shown in Fig. 5, so that the reach 14: of the fabric is farther removed to the rear of the buckle, when the buckle is open, than it is when the buckle is closed, as clearly shown by the dotted line l5, extending' between Figs. 2 and 3. It will therefore be seen that closing' the buckle does not defiect the fabric rearwardly of the buckle, but to the contrary permits the fabric to move to a position nearer the front of the buckle. In Fig. 2, where the buckle is closed, the reach 14; is more nearly in vertical alinement with the rear reach 1G, than it as shown in Fig. l, when the buckle is open. Consequently when reach .ist moves-1 intoline with roach i6 reach LIAG is moved `forwardly instead of rearwardly into such a position. by the act ci' closing the buckle.

lhen the lever l0 is depressed that the parts assume the position shown in Fig. 5, the locking member ll will pass to the rear of the back bar 6, and, temporarily, by that means, it will compress the webbing, but as it passes over the edge of the back bar 6, it releases the webbing, because, then it has brought the teeth l2 into contact with the webbing and the webbing is displaced by this act forwardly and not rearwardly, whereupon reach lli and reach 1.6 are brought into vertical alinernent without rleflectingg' the buckle. "i

Comparing Fig. 2 with Fig. 3, it will be noticed that when the members 11 and 12 are moved to their closed position, more clearly shown in Fig. 5, the webbing is not deflected thereby over the edges of the members 6 and 8, because it is already over the edges of these members, but it is deflected toward their edges and permitted to move forwardly in the act of closing the buckle.

Vhen the locking member 11 of the lever is moved to the position shown in Fig. 5, the teeth are brought into position to re ter with the interdental spaces between .i teeth 9 of the frame fr, to pass therebetween, but the teeth 12 will pass beyond the teeth 9 when the buckle is closed, and, there fore, the webbing` is not forced between the teeth 9 and 12 for the purpose of holdin/ g` it but reach 17 engages the teeth 9 and reach 14 engages the teeth 12 and an effort 'to straighten out these parts of the fabric tends to cause the teeth to more intimately engr the fabric and hold it positively against movement.

It will be observed that the locking member 11 and the teeth 12 are substantially parallel with the buckle lever 10 and not at right angles thereto, as common in buckles of this type.

To open the buckle, to release the weobing, it is necessary to move the lever it forwardly, holding the frame or finger piece A in position, during this action, and to move the locking` member 11 out of the slot 18 in the frame A, or until the locking member 11 has passed the vertical plane in Awhich the teeth 9 are located.

It Will be noticed that the locking member 11 is slightly curved rearwardly and that the teeth 12, while they are not in the same plane as the locking member, beingin front of the locking member when the buckle is closed, as clearly shown in 5, are also curved, so as to cause the points of the teeth to be presented to better advantage to the fabric with which they are in Contact.

Any stress applied between the reaches 16 and 17 and reach 14, tends to straighten the fabric and thereby to draw the fabric into more `intimate contact with the teeth 9 and 12 of the respective parts of the buckle and to hold the buckle more firmly closed, and when the strain is released,

there is no tendency to cause disengagcnicnt of the buckle parts.

lllhile l have herein shown a single cinbodiment of my invention, for Jdie piu-pow of clear disclosure, it will he manifest, ro persons skilled in the art, that omc changggce; may be made in the general :u'ran; cinent and configuration of the parte within the scope of the appended claims.

Having described my invention, what l claim is 1. il buckle having` a traine with a web threading slot theretlnough and forniin'v pintlc bar and a back bar on opposite of the slot, a front bar formed inte with the back bar of the frame :"1 linerefroni to forni i clamp for one ond of a web and han" e upper edge notchcl. and a lever having portions copcruiiug with the pintle bar to form a pivot and owx edge proviilwl with priicci'ions positioned to ic' L 1 ,d i icjvond ihn insidie: in thn iront bar when die buckle is elw-wl and acting to deflect the web firmly againf-t the notcl'ied edge o l the front har to clanni the web.

2. A, buckle comprising a frame formed into a pintle bar and a back bar in the saine plane and a front har in a different plane. the front har havingv a notched edge 'for engaging a web, and a lever pivot/:d tu the pintle bar and having projctlions which register with and pass beyond the novhefl edge of the front bar when Ythe buckle is closed and acting to deflect the web firnilj; against the notched edge of the front bar and allow the reach of the web to more toward the front of the bucl-:lc when the buckle is closed.

3. A buckle comprising a frame slotted to receive a web and 'forni a pintlc har and l'l, lili a back bar in sub:- tantiallj,Y the same plane and having a portion bent lo forni a front bar in a different plane, and a lever hinged to the pintle bar and having an edge \\hich passes beyond the plane of the piutlo and back bars when the buckle is closed to deflect the web tightly against the front har to hold the web against movenicnt.

ln testimony whereof l hcrei'into :uhscribc myv name.
